Mint nutrient deficiency in aquaponics system

Mint    Norway

I have a number of plants: Mint, Basil and Lettuce growing in an aquaponics setup, where the bottom of the roots have access to water from a fish tank.

They definitely look like they are suffering some deficiency but I'm not sure what.
The closest I have found is maybe potassium deficiency?

It is undoubtedly a physiological stress but the challenging issue with aquaponics is that is lacks any nutrients besides what is inputted (compared to soil). So, you need to determine what is in the water. The field of aquaponics is much newer so it is harder to draw from the published literature to see the problem. I would recommend contacting aquaponic companies about this.
